Lathes.-A lathe is provided with a number of automatically fed tool-holders arranged in any desired position on a sliding table 15 which is carried on the bed 12 and which may be moved rapidly to and from the work by means of a pneumatic cylinder 55. The rear end of the table 15 is bored to receive a sleeve 16 carrying a vertical shaft 19 which is driven from a splined worm or spiral gear 21 on a feed shaft 23 and which carries a sprocket 20 for driving the tool carriers. Each tool carrier comprises a flanged base portion 25 bolted in any desired position to the table 15 and carrying a slide 32 which is automatically fed by a screw 39 driven through bevel and chain gearing from the sprocket 20. The feed nut 44 is splined in the slide 32 and a spring 49 is interposed between the feed nut and a nut 48 screwed into the slide. At the end of the forward feed a stop 5') contacts with an adjustable pin 51 to arrest the slide, the spring 49 being compressed whilst the spindle makes a few more revolutions to clean up the cut. One or more tool carriers may be used, one example Fig. 6, showing three tool carries all driven from the sprocket 20 by a chain 36b guided by idlers 52, 53<a>, 54<a> mounted on slides secured to the table.

Title: Apparatus for drying atomized wet material and separating the dried material
IPC: B01D1/18
Filed: 1955-02-04
Abstract: <PICT:0767459/III/1> Apparatus for drying atomized wet material with a gaseous drying medium comprises a drying chamber through which the atomized material and the drying material pass in concurrent flow, and a centrifugal separating chamber to which the outlet end of the drying chamber is connected by an annular opening co-axial with the separating chamber and is provided with guiding devices for imparting to the drying medium passing into the separating chamber the rotation required for the centrifugal separation, the centrifugal separating chamber having a central outlet for the drying medium which has been at least partly freed from the dried material.  In a preferred embodiment the material to be dried is passed through a pipe 9 and is atomized on reaching the drying chamber 2 by striking a rapidly rotating disc 6.  At the same time hot air is added through an annular aperture 10 fitted with guiding devices (not shown) so as to cause the air to rotate in the same direction as in the centrifugal separating chamber 4. The dried material and drying medium then pass through an annular opening 15 fitted with obliquely fitted guiding devices (not shown) which provides increased rotational velocity which gives the necessary separation.  The dry particles fall and are removed through rotary valve 22 and the drying medium rises into cavity 18 and is discharged via a line 19 by suction fan 20.

Abstract: 747,846. Pile drivers. TENSEN, P., and MEENT, A. VAN DE. Feb. 10, 1954. No. 3889/54. Class 68(2) An hydraulicgravity pile driver comprises a ram 1 slidable on a stationary hollow rod 2 which is connected to a high pressure pump, the plunger of which is driven by a spiral - shaped rotary cam instead of the usual crank. The pressure fluid passes through ports 9 to the space between packings 10, 11, the former being carried by the stationary rod 2 and the latter by the ram 1 which is thereby raised in preparation for the working stroke which is by gravity. The amount of pressure fluid required for raising the ram is very small, so that the plunger of the pump need be in contact with the cam for a short time, especially as the area of the pump plunger is large compared with the effective area of the packings 10, 11. This enables the ram to fall by gravity without appreciable resistance from the liquid which to to be returned to the pump.
